[0031] The remote control device, display device and remote control method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the remote control device includes a remote control body 1, an ultra-wideband receiving module 11, a first control module 12 and a radio frequency communication sending module 13, wherein the ultra-wideband receiving module 11 is disposed at one end of the remote control body 1, and is used to receive a ranging signal sent by an ultra-wideband sending module 21 on a display device, and send the ranging signal to the first control module 12; the first control module 12 is disposed in the remote control body 1, and is electrically connected to the ultra-wideband receiving module 11, the first control module 12 is used to determine the ranging signal received by the ultra-wideband receiving module 11 as azimuth data, and send the azimuth data to the radio frequency communication sending module 13, the azimuth data is used to characterize the coordinate information of the corresponding cursor of the remote control body 1 on the display device; the radio frequency communication sending module 13 is disposed in the remote control body 1, and is electrically connected to the first control module 12, and is used to send the azimuth data sent by the first control module 12 to the radio frequency communication receiving module 22 on the display device, so that the display device generates a cursor corresponding to the remote control body 1.

[0033] In the embodiment of the present application, the ranging signal sent by the ultra-wideband transmitting module 21 on the display device is received by the ultra-wideband receiving module 11, and the ranging signal is sent to the first control module 12. The first control module 12 determines the ranging signal as the azimuth data, and then sends it to the radio frequency communication receiving module 22 on the display device through the radio frequency communication transmitting module 13, so that the display device generates a cursor corresponding to the remote control body 1, and performs corresponding operations through the cursor. Since the ultra-wideband communication technology has higher anti-interference ability and higher positioning accuracy, the cursor positioning generated on the display device is more accurate, and the operation fluency of the remote control device is improved.

[0034] It should be explained that ultra-wideband (UWB) technology is a wireless communication technology characterized by using a very large frequency range to transmit data, with higher transmission rate, lower power consumption and better anti-interference ability. In the present application, an ultra-wideband receiving module 11 is set in the remote control device, and an ultra-wideband transmitting module 21 is set in the display device, so that the cursor position corresponding to the remote control device in the display device is accurately calculated through the ranging signal transmission between the two, while avoiding inaccurate positioning due to interference from other signals.

[0035] It should be explained that the radio frequency (RF) communication sending module 13 is electrically connected to the first control module 12. Specifically, the radio frequency (RF) communication sending module 13 can use communication technologies such as Bluetooth and WIFI to achieve wireless communication with the radio frequency (RF) communication receiving module 22. Thus, the radio frequency (RF) communication sending module 13 sends the position data to the radio frequency (RF) communication receiving module 22 on the display device, and the display device generates a cursor corresponding to the remote control body 1 according to the position data, so that the user can use the cursor to perform corresponding operations, such as precise pointing, marking, writing, drawing, turning pages, etc.

[0036] In a specific application, the first control module 12 is electrically connected to the ultra-wideband receiving module 11, and can be specifically a microcontroller unit (MCU) or a control chip, etc. The first control module 12 receives the ranging signal sent by the ultra-wideband receiving module 11, and then resolves the ranging signal into azimuth data, which is used to represent the coordinate information of the corresponding cursor of the remote control body 1 on the display device.

[0037] It needs to be explained that in actual applications, at least three ultra-wideband transmitting modules 21 are arranged on the display device, and the relative position of each ultra-wideband transmitting module 21 on the display device is known. The ultra-wideband receiving module 11 respectively receives the ranging signal sent by the ultra-wideband transmitting module 21, and the ranging signal actually refers to the distance between the ultra-wideband receiving module 11 and the ultra-wideband transmitting module 21. Then, the first control module 12 establishes a spatial coordinate system according to the distance between the ultra-wideband receiving module 11 and the ultra-wideband transmitting module 21, thereby determining the orientation data. The orientation data specifically refers to the corresponding coordinate position of the remote control body 1 on the display device.

[0038] It can be understood that the ultra-wideband transmitting module 21 sends a ranging signal with a timestamp, the ultra-wideband transmitting module 21 sends the ranging signal at time t0, and the ultra-wideband receiving module 11 receives the ranging signal at time t1, so that the distance d between the ultra-wideband transmitting module 21 and the ultra-wideband receiving module 11 can be calculated as: d=v(t1-t0), where v is the propagation speed of the ranging signal. The distance between each ultra-wideband transmitting module 21 and the ultra-wideband receiving module 11 can be calculated in this way.

[0039] like Figure 3 As shown, take the display screen 25 of the display device as 163.5cm×92cm in size, and four ultra-wideband transmitting modules 21 are provided on the display device as an example, wherein three ultra-wideband transmitting modules 21 are provided at three corners of the display device. Since the overall size of the display device is known, the relative position data of each ultra-wideband transmitting module 21 can be obtained. The corresponding cursor position of the remote control body 1 on the display device is M. The distances between the ultra-wideband receiving module 11 and the four ultra-wideband transmitting modules 21 are respectively the first distance measuring line a1, the second distance measuring line b1, the third distance measuring line c1 and the fourth distance measuring line d1, forming a spatial quadrangular pyramid shape. The ultra-wideband receiving module 11 on the remote control body 1 is at the vertex of the quadrangular pyramid, and the corresponding quadrangular pyramid height is the line connecting the remote control body 1 and its corresponding cursor on the display device. Further, according to d=v(t1-t0), it can be calculated that a1=85.73cm, b1=72.97cm, and c1=144.92cm. Figure 3 As shown, M1 is a feature point of the ultra-wideband receiving module 11 on the remote control body 1, and M2 is a cursor feature point corresponding to the remote control body 1 on the display device.

[0040] like Figure 4As shown, the first distance measuring line projection a2, the second distance measuring line projection b2, the third distance measuring line projection c2 and the fourth distance measuring line projection d2 correspond to the orthographic projections of the first distance measuring line a1, the second distance measuring line b1, the third distance measuring line c1 and the fourth distance measuring line d1 on the display screen 25 of the display device, respectively. With the lower left corner as the origin, a Cartesian coordinate system is established to form an X axis, a Y axis and a Z axis. The coordinates of M1 are set to M1 (x, y, z), and the coordinates of M2 are M2 (x, y, 0), as shown in FIG. Figure 4 As shown, according to the Pythagorean theorem, we can get: 2 +y 2 =b2 2 ;x 2 +(92-y) 2 =a2 2 ; (163.5-x) 2 +(92-y) 2 =c2 2 Since a2, b2, c2 and d2 correspond to the orthographic projections of a1, b1, c1 and d1 on the display screen 25 of the display device, respectively, it can be obtained that:

[0041] x 2 +y 2 +z 2 =b1 2 =72.97 2 ;

[0042] x 2 +(92-y) 2 +z 2 =a1 2 =85.73 2 ;

[0043] (163.5-x) 2 +(92-y) 2 +z 2 =c1 2 =144.92 2 ;

[0044] Based on the above three equations, the specific coordinate values ​​of points M1 and M2 can be calculated. At the same time, a fourth equation can be established based on d1 and d2 for verification. If the calculation results are significantly different, the calculation signal is determined to be incorrect and the calculation is performed again. It should be noted that the above values ​​are only exemplary descriptions, and the specific values ​​can be changed according to actual conditions.

[0045] It should be noted that the ultra-wideband sending modules 21 on the display device may be numbered so that each ultra-wideband sending module 21 sends a ranging signal in a preset order and interval time to avoid mutual interference.

[0046] like Figure 5 As shown, in some embodiments of the present application, the remote control device also includes an inertial measurement module 14, which is disposed in the remote control body 1 and electrically connected to the first control module 12. The inertial measurement module 14 is used to obtain the angle attitude data of the remote control body 1 and send the angle attitude data to the first control module 12; the first control module 12 is also used to determine the coordinate pointing data based on the angle attitude data and the azimuth data.

[0047] In an embodiment of the present application, the angle posture data of the remote control body 1 is obtained through the inertial measurement module 14, and the angle posture data is sent to the first control module 12. The first control module 12 determines the coordinate pointing data based on the angle posture data and the azimuth data, so that the coordinate information of the cursor corresponding to the remote control body 1 can be corrected in real time, thereby improving the controllability.

[0048] It should be explained that the coordinate pointing data refers to the coordinate information of the cursor corresponding to the remote control body 1 on the display device. In other words, the coordinate pointing data is the correction made by the first control module 12 to the orientation data according to the angle posture data.

[0049] For example, Figure 3 and Figure 4 As shown, according to the above, taking the ultra-wideband receiving module 11 at M1 as an example, the coordinates of the cursor are at M2 at this time. When the front end of the remote control body 1 (i.e., the location where the ultra-wideband receiving module 11 is set) does not move, the rear end deflects, so that the remote control body 1 is re-pointed to M3. At this time, the remote control body 1 deflects α in the X direction and β in the Y direction. Since the vertical distance (z) between the remote control body 1 and the display device has not changed, the coordinate value of M3 can be obtained as (x+ztanα, y+ztanβ, 0) according to the Pythagorean theorem. Therefore, the coordinate information of the cursor of the remote control body 1 on the display device can be corrected in real time according to the angle posture data of the remote control device, thereby improving the accuracy of the remote control device and improving the controllability of the remote control device.

[0050] It should be explained that the inertial measurement module 14 is specifically an IMU (Inertial Measurement Unit) which includes an accelerometer and a gyroscope, so as to obtain the three-axis acceleration and three-axis angular velocity in the coordinate system of the remote control body 1 itself.

[0051] In some embodiments of the present application, the first control module 12 is also configured to determine the movement information of the cursor on the display device based on the ranging signal and the angle posture data, and send the movement information to the display device through the radio frequency communication sending module 13, so that the display device selects the corresponding operation item according to the movement information.

[0052] In the embodiment of the present application, the first control module 12 is also configured to determine the movement information of the cursor on the display device based on the ranging signal and the angle posture data, and send the movement information to the display device through the radio frequency communication sending module 13, so that the display device selects the corresponding operation item according to the movement information, thereby realizing richer operations on the display device, improving the controllability of the remote control device, and enhancing the user experience.

[0053] Exemplarily, the movement information of the cursor on the display device is determined based on the ranging signal and the angle posture data. The cursor of the remote control body 1 on the display device may form a moving trajectory, and then the movement trajectory information is sent to the display device, and the display device generates a highlight mark on its display screen 25. In other words, the first control module 12 generates a line on the display device according to the movement and angle rotation of the remote control body 1, thereby realizing the line drawing operation.

[0054] Of course, related operation items may also include turning pages, writing, etc. Technical personnel in this field may set them according to actual needs, and this application does not impose any restrictions on this.

[0055] like Figure 1 As shown, in some embodiments of the present application, the remote control device further includes a laser emission module 15, which is disposed at one end of the remote control body 1 and electrically connected to the first control module 12, and is used to generate a laser spot.

[0056] In the embodiment of the present application, by providing a laser emitting module 15 at one end of the remote control body 1, it is convenient for the user to generate a corresponding laser spot according to actual needs for use in demonstration, thereby improving the convenience of the remote control device.

[0057] In a specific application, the laser emitting module 15 can be set at the same end of the ultra-wideband receiving module 11, or at two different ends. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on this.

[0058] In some embodiments of the present application, the remote control device also includes a power module, which is electrically connected to the ultra-wideband receiving module 11, the first control module 12, the radio frequency communication sending module 13, the inertial measurement module 14 and the laser emission module 15, and provides power to the above modules.

[0059] In an embodiment of the present application, a power supply module is provided to provide the electrical energy required by each module for the normal operation of the entire system. The power supply module may specifically include a battery, a DC conversion module and a voltage stabilizer.

[0060] like Figure 1As shown, in some embodiments of the present application, the remote control device also includes a control component 16 and a functional module 17. The control component 16 is arranged in the remote control body 1 and is associated with the first control module 12, and is used to control the start and stop of the laser emission module 15; the functional module 17 is associated with the first control module 12, and is used to perform corresponding functions on the display device based on the user's input, and the functional execution includes but is not limited to: at least one of tuning, turning pages, etc.

[0061] In the embodiment of the present application, by setting the control element 16 and the functional module 17 in the remote control body 1, the start and stop of the laser emission module 15 can be controlled according to the user's operation, which is convenient for the user to use; at the same time, the display device can perform corresponding functions according to the user's input, such as adjusting the volume, turning pages, etc., which improves the controllability and convenience of the remote control device.

[0062] In a specific application, the control component 16 and the functional module 17 can be at least one of a push button, a toggle button, a touch button, a touch pad, etc. Those skilled in the art can set them according to actual needs, and this application does not impose any restrictions on this.

[0063] It should be explained that the functional module 17 also includes a switching button, which is used to switch between multiple control modes of the remote control device, such as: physical cursor pointing mode: specifically, the laser emission module 15 works, so that the user guides the audience's eyes by projecting a laser spot; or multi-function simulation cursor mode: specifically, a virtual cursor is generated on the display device, and the virtual cursor is used to achieve functions such as precise pointing and marking.

[0064] like Figure 5 As shown, in some embodiments of the present application, the remote control device also includes an infrared transmitting module 18, which is disposed in the remote control body 1 and electrically connected to the first control module 12, and is used to pair with the infrared receiving module 24 of the display device to realize remote control of the display device.

[0065] In the embodiment of the present application, the infrared transmitting module 18 is provided to be paired with the infrared receiving module 24 of the display device, thereby realizing remote control of the display device, improving the stability of the remote control device for remote control of the display device, and improving the user experience.

[0066] In a specific application, the infrared transmitting module 18 and the radio frequency communication sending module 13 together constitute the interactive interface between the remote control device and the display device. The infrared transmitting and radio frequency transmitting parts of the remote control device combined with the infrared receiving and radio frequency receiving parts of the display device jointly realize the remote control of the display device.

[0067] like Figure 2 and Figure 6As shown, some embodiments of the present application further propose a display device, including a display body 2, at least three ultra-wideband transmitting modules 21, a radio frequency communication receiving module 22 and a second control module 23, the radio frequency communication receiving module 22 and the second control module 23 are arranged in the display body 2, at least three ultra-wideband transmitting modules 21 are respectively arranged at any three different positions of the display body 2, the second control module 23 is electrically connected to the ultra-wideband transmitting module 21 and the radio frequency communication receiving module 22; at least three ultra-wideband transmitting modules 21 are communicatively connected to the ultra-wideband receiving module 11 of the remote control device for sending ranging signals; the radio frequency communication receiving module 22 is communicatively connected to the radio frequency communication transmitting module 13 of the remote control device for receiving data; the second control module 23 is used to generate a cursor corresponding to the remote control body 1 on the display screen 25 of the display body 2 based on the received azimuth data.

[0068] In the embodiment of the present application, at least three ultra-wideband sending modules 21, a radio frequency communication receiving module 22 and a second control module 23 are provided on the display body 2 of the display device, so that a corresponding communication connection can be formed with the corresponding ultra-wideband receiving module 11 and the radio frequency communication sending module 13 on the remote control device, and a ranging signal is sent through the ultra-wideband sending module 21, and azimuth data is received through the radio frequency communication sending module 13, so that the second control module 23 can generate a cursor corresponding to the remote control body 1 on the display screen 25, thereby realizing efficient and stable remote control, and performing corresponding operations according to user needs.

[0069] In a specific application, the number of the ultra-wideband transmission modules 21 can be 3, 4, 5, 6, etc., at least three of which are set at any three different positions of the display body 2, for example, at three corners of the display body 2, so as to facilitate corresponding calculations. Those skilled in the art can make settings according to actual needs, and this application does not limit this.

[0070] It should be explained that the display device can specifically be any digital display device that can interact with the remote control device, such as a television, a projector, a visual display screen, etc. Technical personnel in this field can choose according to actual needs, and this application does not impose any restrictions on this.

[0071] like Figure 6 As shown, in some embodiments of the present application, the display device also includes an infrared receiving module 24, which is disposed in the display body 2 and electrically connected to the second control module 23, and is used to pair with the infrared transmitting module 18 of the remote control device to achieve a response to the remote control device.
